About this app

Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Duo Mobile also has a companion app for Wear OS, Duo Wear, making secure authentication even more convenient on your smartwatch.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.

Ratings and reviews

Overall it works decently well. A few annoyances, but mainly that if you click the accept button in the notification panel and it doesn't detect a Wi-Fi/cellular signal (even though it's always there) it pops up the app with a failure notification, but accepting the failure notification CLOSES THE APP. When trying to accept a login attempt against a timer this is majorly annoying and serves absolutely no purpose to have it close after that... it does this frequently.

This app has been awful as an IT admin. Enrollments very often don't work for no apparent reason, and refuse to give any meaningful error data. Users softlock themselves if the enrollment process gets interrupted at any point, and then their partial setup has to be completely reset from our end before they can try again. We've been getting countless calls about the setup just failing or refusing to proceed for no reason. Once set up, the app occasionally fails to send push notifications.

would give 0 stars if i could. I've had to use this app for years at school, and it has never worked for a period longer than a week. The web browser support is awful, it is impossible to reach customer service. The app regularly decides that the settings on my phone or computer are wrong and it will not work, even when I haven't changed the settings ever and it worked just fine. Literal garbage. Cannot wait to be done using it.
